Hi
I have seen several questions on this already but haven't been able to sort my
issue. My problem is that multi-word synonyms aren't behaving as I would
expect. I have copied my field type definition at the bottom of this message,
but the relevant synonym filter is here (used at index time):
<filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt"
ignoreCase="true" expand="true" tokenizerFactory="solr.KeywordTokenizerFactory"
/>
Say I have synonyms.txt setup like this:
syrup,sugar syrup,stock syrup
When indexing the text 'syrup', the 3 phrases are treated equivalently as
expected. I can see this in the Index Analyzer as they all occupy the same term
position.
But if all of the synonyms are a phrase, it doesn't work.
e.g. synonyms.txt looks like:
simple syrup,sugar syrup,stock syrup
Now when putting the text 'simple syrup' into the Index Analyzer I can only see
the original term listed. It is not finding the synonyms.
Anyone know how to fix this?
